Purity assay of organic solvents (GC-FID, Karl Fischer and ICP-MS)
Determination of solvent purity by GC-FID technique and Karl Fischer titration and metal screening of the sample with ICP-MS technique. Purity assay is performed by analyzing the sample with GC-FID and comparing the area of the solvent signal to the combined area of all peaks. The purity of the solvent sample is expressed in percentage (%). Karl Fischer titration is used to determine the amount of water in the solvent. The amounts of the following metals in the sample is determined with ICP-MS: Na, Mg, K, Ca, Li, Be, B, Al, Si, P, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Zr, Nb, Mo, Ag, Cd, In, Sn, Sb, Te, Cs, Ba, Hf, Hg, Tl, Pb, Bi, U. In the results, the elemental concentrations are expressed in unit mg/kg.
